i Application filed June 1, 1908. Serial No. 436,128.

To all whom it me 1 concern:

Be it known that I, Loris AUGUSTIN, a i subject of the King of Great Britain, resident 1 of St. Simon street, in the town of St. Ilyacinthe, in the Province of Quebec, in thel Dominion .of anada, have invented certain new and useful linprm'enients in Retorts, of

which the following is a specification. The invention relates to improvements in j retoits, as described in the present specilication and illustrated in the accompanying drawings that form part of the same. 'The invention consists essentially in the novel arrangen'ient. and construction of parts i whereby a cylindrical casing is rcvolubly arranged over a fire box and rotated to expose a complete ciroumferentiul surface to the heating gases at cat-h revolution, l The objects of the invention are to derive E the fullest benefit from the fuel consumed, to distribute thc'he'at evenly throughout the contents of the retort casing, to facilitatethe charging and emptying of said casing and generally to devise a simple and cl'l'ecthei machine. I In the drawings, Figure 1 is a front eleva. i tion of the retort. big. 2 is a sectional side i elevation sho'ning the length broken away centrally for the better illustration of the .0 front and rear ends. Fig. 3% is a sectional plan View of the ,machine broken away centrally to show the arrangement at the front and rear ends. Fig. 4 is a cross sectional View through the line A- l l in Fig. 3. Fig. 5 is a cross sectional View through the line (I Din Fig. 3. r

.Like nun'urrals of reference indicate corresponding parts in each figure.

Referring to lllI5,(l1'tLWlllgS, 1 is the c \lin-- 0 drical casing having the externally threaded front and rear ends 2 and 3 respectively. 4 is a collar having its inner wall threaded correspondingly and turning on the front threaded end 2 of the casing 1, said collar 5 having the outwardly extending slotted lugs 5 therefrom. 6 are eye-bolts threaded and having their eye ends inserted in said slotted lugs, held therein by the pins 7, the threaded ends of said bolts extending forwardly beyond the casing. I j

8 is the front head of the casing 1 having the laterally extending lugs 1) into which the threaded ends of the bolts 6 are introduced. 10 are nuts on the threaded ends of the bolts t5 and rigidly securing said head 8 to the eas- 11 is a stub shaft projecting outwardly and centrally from the head 8 and rigid therewith.

12 is the rear head of the casing 1 having the inwardly extending flange 15 threaded in E its interior wall correspondingly to the rear threaded end 3 of the casing 1 and screwing on said casing, and the flange 14 extending laterally beyond the flange 13, and flange 14 at the outer edge thereof being formed into the teeth 15 and forming the said head 12 into a large sprocket wheel, said head 12 also having the central orifice 16 th'ercthrough from the edge of which projects the shaft 17, I said shaft being hollow and rigld with said head.

18 are sockets formed on the inner face of the head 12 and pr ferably part with said head. i

It) are sockets formed on the inner face of the front head N 'n'el'crably forming part. therewith.

It will now be seen that a cylindrical retort casing is formed having removable heads and central shafts extending from each of said heads, by means of which the said retort may be journaled, and a sprocket wheel, at one end, by means of which said retort may be operated in its journal bearings.

21) is a frame for holding the charge in the cylindrical casing 1, in which 2.1 are disks having the central holes 22. the said disks bein joined by the longitudinal plates 23 rigidly secured to said. disks and radially arranged thereon extending from the edge 1 thereof inwardly to the central hole 22.

24 are rods rigidly secured to the outeirfaees 3 of the disks 2] and extending longitudinally therefrom, the said disks, plates and rods.95 forming a frame to receive the cl'ia'rge of material to be baked in the retort, the outer ends of the rods 24 fitting into the sockets 1S and 1!) respectively when the retort is completely closed. In filling the said charge frame with material. a core piece 25 is inserted through the holes 22 and remains therein while the said frame is being filled with peat or other material. The said core Piece 25 is removed )reyious to baking the material, the latter liolding together sufliciently to leave the longitudinal hollow in the center through which the gases produced extending from the said material by the heat find psssage.

26 is the brick portion of the furnace structure, having the fire box 27 and heating gas passages 28 through to the line 29, the retort v casing chamber 30 being formed in said brick Work, and crossing said heating passages 28.

31 is a front plate of the furnace extending upwardly having the furnace doors 32 and 33 therein arranged and the circular opening 34 leading into the casing chamber 30, the annular flange 35 extending inwardly from said plate around the inner wall of said cham- 36 is a ring platearranged at the'inner end of the flange 35. Y

37 are pins rigidly secured in the front plate 31 around the o ening 34 and extending inwardly and rigi ly secured in the ring plate 36. I x v 38 are rollers journaledon the pins 37.

39 is the rear plate of the furnace having a circular opening 40 therethrough in alinement with the circular opening 34, said open ings being of slightly larger dimensions than the casing 1, so that the said casiiig turns freely in said openings, the annular flange 41 extending inwardly from the rear plate 39 at the edge of the opening and encircling said 30 casing 1, when the said casing is in position in the casing chamber '30, the rollers 38 at the front end engaging the periphery of the retort casingl as it revolves. 42 is the hearing at the front end for the shaft 11 from the 3 front head 8 to the said cylindrical :casing, said bearing 42 having the stud 43 extending downwardly therefrom.

4A is an arm'swin ing'laterally from the bracket 45, the latter eing rigidly secured to instant plate 31 to one side of the casing "chamber 30,

46 is a vertical journal orifice in the outer extremity of the arm 44 and receiving the stud 43, conse 'uently providing a pivotal 45 and self-ahning )earing tor the shaft 11, supporting the retort casing 1 at the front end.

It Will readily be understood that on the removal of the head 8 from the retort casing 1, which is accomplished in a very simple manner by removing. the nuts 10 from the eye-bolts 6 and the said eye bolts from the slotted lugs 9, that the said head and shaft 11 journaled in'the bearim 42 may be swung; away from the said eyhndrical casing and leave the said casing quite open at the front end. The core or charge frame may then be taken out and rc-filled after the removal of the charred remains of the material, from which gas has been produced. 47 is a bracket secured to the'r'ea'r plate 39 outwardly and upwardly therefrom having at the upper end a vertical journal orifice pi'votally sup orting the hearing 48, in Which-theshaft 7 1s ournaled forinin g the-rearjournaled support for the casing 1.

ceases The shaft 17 extends beyond the hearing 48 and the pipe 49 extends thereimo, the gland 50 being formed hctivcen said gas pierand said shaft 17. 51 is a pipe jointjoiningg to the gasometer or storage tanks.

52 are tie rods extending thronga the st run ture from the front plate 3] to the r -ar plate 39. The operation of the machine is fairly xv -ll explained in the detailed description of inparts, but a few advantages may he lflz'ntioned to more clearly prove the usefulnesof the invention. The brick structure is an arranged that the heating gases from. the in" box pass around and about the eyliniiriixz casing at the central portion thereof, ri-- chamber for said gases extending :li'm' said casing and leading to the flue, thus narily the retort casing 1 will be heated pletely therearound without revolving, the'heat would he very unevenly (livid the interior of said retort casing, the o the said casing is rotated by a chain om said casing in its journal bearings very slowly during the baking process. It will he tine: seen that the charge of poet or other solstance gathered in the frame forithat particular PHI)OSB will be evenly heated and baked throughout, with the consernienco that when the said charginp frame is removed, the has been drawn away from cvdry 'part of said peat, no n'iatter where the said )eat was contained in the charging frame, ieaving nothing but the charred remains in the form of coke. The facility with whirl: the charge frame may be removed must be particularly emphasized, s that o .eration can be done wine the 0&8 ing, said casing having a he: n at the 1" ront portion thereof on the rollers ournnlerl on pins from the front plate and extending in- Wardly, and further it may he :nentiom. that the said retort casing itself is quire has;
